Volume of a Cube = s^3
The volume of this cube is 2^3 = 8.
Volume of a cylinder: A cylinder is a uniform solid whose base is a circle.
Given base radius r and height h, the area of the base is πr^2 , and so the volume
formula is this:
Volume of a Cylinder = πr^2 h
In the cylinder above, r = 2 and h = 5, so
Volume = π(2^2 )(5) = 20π
Example 3 gives you the volume of a uniform solid and asks for the surface
area.
